Why the study?
Does the use of coronary artery calcium (CAC) scoring and coronary CT angiography (CTA) improve prognostic assessment and patient management compared to risk factor-based scores alone in patients without prior coronary artery disease?

Non-invasive imaging with CAC scoring and coronary CTA provides direct visualization of coronary atherosclerosis, offering superior prognostic value and personalized risk assessment to guide preventive therapies compared to traditional risk factor calculators.
May refine risk stratification in primary prevention; leaves open whether imaging-guided therapy improves outcomes in RCTs.
Clinicians often use risk factor-based calculators to estimate an individual's risk of developing cardiovascular disease. Non-invasive cardiovascular imaging, particularly coronary artery calcium (CAC) scoring and coronary CT angiography (CTA), allows for direct visualization of coronary atherosclerosis. Among patients without prior coronary artery disease, studies examining CAC and coronary CTA have consistently shown that the presence, extent and severity of coronary atherosclerosis provide additional prognostic information for patients beyond risk factor-based scores alone. This review will highlight the basics of CAC scoring and coronary CTA and discuss their role in impacting patient prognosis and management.
